Joining broken Flex Circuit material 1

[dananay]

My client repairs medical devices. We have 16 and 32 conductor flex circuits on a .004" pitch and .005" thick (substrate) that are fatigue-broken. (Replacing the flex circuit is out-of-the-question because the terminations are potted.) I believe someone may have expertise in the repair of broken flex circuits. I am interested in any applicable info or experience. I want to generate some ideas and try to develop a repair process. Can you share your experience please?

Thank you for your kind reply.

It's the 4mil pitch that is a BIG problem for repairs.

Tough to imagine, this is one of those things where a picture would be mandatory. It sounds like it was designed for the end result.

I can't imagine any repair having the durability required, unless maybe you expose the traces on both sides of the injury, fuse a foil patch over all, then laser trim.

I would think that the only way the economics would work would be to logically deduse the potted element, remove and replace with a custom device, complete with flex circuit.

auto.. Now that's a good idea. Just reverse the board and reuse the parts. I like that.
